Memory Inspector display enhancements

[jreineckearm]

Description

As discussed during the last CDT Cloud meeting, I'd like to share some thoughts on potential display enhancements which could make the Memory Inspector even more powerful than it is already today.

• [x] https://github.com/eclipse-cdt-cloud/vscode-memory-inspector/issues/62 (show/hide radix prefix, change radix)
• [ ] #118
• [x] #73
• [x] #74
• [x] #75
• [x] #76
• [ ] An extension point for more CPU architecture specific representations, e.g. special floating or fixed point formats. Covered by #77?
• [x] Selectable word endianess, for example if viewing a memory buffer for a peripheral which operates with a different endianess than the CPU. Covered by https://github.com/eclipse-cdt-cloud/vscode-memory-inspector/pull/93
• [x] Show most common formats for a selected word in a separate area. Covered by https://github.com/eclipse-cdt-cloud/vscode-memory-inspector/pull/87
• Configuration of physical access size in bytes. (Understood that currently not supported by MS-DAP). TODO: move to separate issue, out of scope for this one here due to dependency to MS-DAP updates. Moved to separate issue #104

At Ericsson, we're currently working on reintroducing the hover system that (among other things) displayed values in different formats, so we'd be happy to take on

Display of different data representations (decimal, octal, binary, float, double, signed vs unsigned, etc)

@gbodeen, re: some possible format additions.

[colin-grant-work]

Configure word size in bytes. As I understand this is currently fixed to 1-byte words.

It would be nice for this one if it were included as an extension point for debuggers that could answer a query about word size for a given session.

That would be awesome, thank you @colin-grant-work ! Would this agree with your plans, @planger ?

I fully agree. Ideally, this knowledge would be transported via the MS-DAP protocol. Need to investigate which would be the best type or response. It certainly will have its charm also for other windows and debug functionality.

A short-term/intermediate alternative could be to add it as another setting. That could later pick up knowledge from the debugger through MS-DAP with an auto setting. Finding a good default for this setting may become a challenge. Maybe it could be steered by an agreed debug launch configuration item like it's used for description files for the Peripheral Inspector extension?

Sure, that sounds great! I'll comment on https://github.com/eclipse-cdt-cloud/vscode-memory-inspector/issues/66 with our initial thoughts to keep the discussion in the right place.
